I only realized I was the protagonist of a mafia novel after I met my husband, and the mafia boss, Lucien Vaughn, was a traveler from another world. According to the rules of his world, he wasn't allowed to develop romantic feelings for anyone in the story. However, the moment he saw me, he fell in love. And every time his heart stirred for me, he suffered pain so intense it felt as if his soul were being torn apart. He endured it ninety-nine times. Then, one day, I was kidnapped by a rival mafia family and taken to South Merica, where I suffered brutal torture. Yet somehow, I managed to escape and hide in a basement. As I listened to my enemies raging outside and searching for me, I quickly used the secret method Lucien had taught me to contact the world beyond this one. The connection worked, and through it, I overheard a conversation between Lucien and one of his friends from the other world. “Lucien, I thought Olivia was the person you loved most! How could you arrange for your enemies to kidnap her?” Lucien's voice was calm and detached. “I didn't have a choice. If I hadn't done it, then Emily Carter would've suffered in this storyline instead. She’s only a supporting character. She would’ve died. “But Olivia is the protagonist. The storyline will protect her. Once this story’s mission is completed, I'll finally be able to stay in this world forever. And when that happens, I'll make it up to Olivia." Tears streamed down my face. My heart felt as if it had been ripped apart, leaving behind nothing but pain and despair. So, when my enemies finally smashed open the basement door, I didn't struggle or run.

Sadie Ozoa wants to chase her dreams and doesn’t want to take no for an answer, but it feels like she doesn’t have a choice. But unexpected decisions they made had created unfaithful circumstances that have brought two different individuals together. Next unthinkable move: run as far away from the situation that could have led to their wishes. They don’t know how they ended up walking together and they don’t know why. But all they want to do is to escape from the environment they were surrounded in. Anya and Sadie thought they would be distant but with every step they took, they started to know so much about each other and what they have one thing in common: they hated how the world has become. They then thought what if they rebuild Earth where it is all ruled by them--and only both of them. The two then thought what if we start to make it a reality? As they go on the journey to create their own world, Anya sees that Sadie is more than an outcast and Sadie sees that Anya is more than just a star--they are each other’s world. But with the world that is against their odds, will they be able to show their truth? In this first debut comes a coming-of-age story about realizing that in order to survive the world, you must choose whether to follow the rules or break them for the sake of doing something right.

I have always been interested in nature and loved taking care of animals but never thought this little interest of mine will land me into a world , I never knew about.
